MULTILAYER CERAMIC CAPACITOR AND INTERNAL ELECTRODE PASTE USED FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain an internal electrode paste by which internal defects are hardly produced at the time of manufacturing a multilayer ceramic capacitor and a multilayer ceramic capacitor using it. SOLUTION: A dielectric material and an internal electrode paste are prepared for obtaining a dielectric ceramic layer 12 and internal electrodes 14 forming a substrate 16 of the multilayer ceramic capacitor 10. Conductive powder and ceramic powder corresponding to 5-20 wt.% of it are used for the internal electrode paste. The shrinkage start temperature of the ceramic powder is within the range of +50 deg.C-+100 deg.C with respect to the shrinkage start temperature of the dielectric material. The same composition as the ceramic powder added to the internal electrode paste is found in the internal electrodes 14 of a completed ceramic capacitor 10.
